Be it known that I, PERL E. PAISLEY, a citizen of the United States, residing at Bellaire, in the county of Belmont and State of Ohio, have invented a new and useful Projectile, of which the following is a specification.

This invention relates broadly to projectiles, and more specifically to an anti-heating nose for explosive-carrying high-speed artillery projectiles.

The primary object is to provide a projectile with a removable windshield having vents therein designed to allow the free passage of air between said shield and the main body of the projectile in order to prevent heating of said projectile due to friction with the atmosphere.

A further object of this invention is to provide a device of the character mentioned which will offer a. minimum of resistance to the passage of the projectile through the atmosphere.

In describing my invention in detail,

" reference is had to the accompanying drawings, in which Figure l is a longitudinal sectional view of an artillery projectile embodying my invention; and

Figure 2 is a transverse section of the same on the line 22, Figure 1.

Referring to said drawings, in which like designating characters distinguish like parts throughout th several views, the numeral 1 indicates the main body portion of a projectile of ordinary type having an interior chamber 2 for the reception of an explosive.

Secured to the forward end of said projectile and completely covering its nose 3, is a shield or cap Al. Said shield is preferably screwed to said body 1, as by means of threads 5. The forward end of said shield is provided with an axial aperture 6 through which air is forced in the passage of the projectile through the atmosphere, After passing through said aperture the air expands within the relatively larger chamber 7 provided within said shield, and thence passes outward through a. plurality of vents 8 provided in said shield near the rear end thereof. If desired, the vents 8 may be directed outward through said shield at right angles with the axis of said projectile. However, in order to lessen the resistance-which the outgoing ai r'affords to the passage of the projectile through the atmosphere, I prefer to direct said vents backward at an acute angle with the axis of the projectile, substantially as shown. This construction also, by reason of the suction it affords in the passage of the projectile through the atmosphere, materially assists in evacuating said chamber 7 of its rarefied or expanded air.

Thus it will be understood that the air within the chamber 7 will, by reason of its expansion therein, be considerably cooler- 2. A windshield for an explosive-carrying projectile, having an aperture in the forward end thereof and a plurality of vents toward the rear end thereof, said aperture and vents connecting the exterior of said windshield with an interior expansion chamber, said vents being directed outwardly and rearwardly at an acute angle with the axis of said windshield.

3. A windshield for an explosive-carrying projectile, having an aperture in the forward end thereof and a plurality of vents toward the rear end thereof, said aperture and vents connecting the exterior of said windshield with an interior expansion chamber, said vents being directed outwardly and rearwardly at an acute angle with the axis of said windshield, said windshield being rigidly fastened to the nose of an explosive-carrying projectile.

4. The combination with an explosivecarrying projectile, of a windshield rigidly attached to said projectile and covering the nose thereof, said windshield being so shaped as to form an expansion chamber for air forward of and around said nose,

said chamber having connection with the exterior of said windshield by an axial aperture in the forward end of said windshield.

5. The combination with an explosivecarrying projectile, of a windshield rigidly attached to said projectile and covering the nose thereof, said windshield being so shaped as to form an expansion chamber for air forward of and around said nose, said chamber having connection with the exterior of said windshield by an axial aperture in the forward end of said windshield and by a plurality of vents located near the rear end of said windshield.

6. The combination with an explosivecarrying projectile, of a windshield rigidly attached to said projectile and covering the nose thereof said windshield being so shaped as to form an expansion chamber for air forward of and around said nose,

PERL E. PAISLEY.
